What prompted this question is some Japanese TV service ended this past weekend for a relative and the word to describe the static noise was "sand storm".
Thought it might be interesting to hear what it's called elsewhere.
So Japan still uses analog broadcast TV? Maybe it's different for other US TVs, but since the switch to the digital broadcast system my TVs show black when a channel is not available. Snow has gone the way of the old test pattern of years ago.
Analog went offline in Japan around 2010/2011 if my memory serves me correctly, but some still have digital receivers that works with the RF jack. Now more or less it's out of style and the static is just proverbial.
